#!/bin/bash
# Create an openSUSE image with lvm on dm-crypt partition
# 
# Theory of operation:
#  This script uses zypper from the host to resolve dependencies 
#  for zypper which runs within the appliance. If zypper on the host
#  is too old, it will be unable to handle repo data from 13.1:
#    http://lists.opensuse.org/zypp-devel/2013-11/msg00000.html
#    "[zypp-devel] Package conflicting with itself"
#  For this reason zypper from 12.3 can be used to install the pattern
#  of the final repo.
#  First the dependencies of zypper are resolved, the required packages
#  are downloaded and extracted with unrpm. Now the guest is started and
#  the partitions in the diskimage are prepared. Then the extracted
#  package content is copied into the guest. Once that is done zypper
#  inside the guest will install the base pattern and a few extra packages.
#  Finally the bootloader grub is configured. Once all that is done
#  kvm is started. If all goes well a login prompt appears.
#  The password for the crypted partition is "123456".
#  The password for root is "root".
#  The guest has also network access to the outside.
#
# Expected runtime: ca. 200 seconds
# Requires at least 1.24.5 because this includes the required crypt modules
#
# Expected output:
# guest should start
# no "obvious" errors should be shown during the disk operation
# at the end kvm is started with the generated disk image
# login should be possible
#
